UltArc's got it right- a stealth camper is the best way to go. A box truck, van or even a hatch can be equipped for living much more cheaply than buying an RV. You've got the ease of not having to find living quarters or not having to find a place to set up- you also don't have to set it up. You don't have the stigma of being an RV and obviously camping out, you're just a car or van that's parked somewhere.

My BIL's camper for years was his Mazda pickup with a cap, and he had a really good setup going on. He wanted more space and has a pickup camper in it now, but his DIY worked really well.
